SHUTTLE BOX FOR LOOMS.

Application filed April 23, 1924. Serial No. 708,554;

To all whom it may concern:

Be it known that I HARRY A. DAVIS, a

States, and a resident of -Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Shuttle Boxes for Looms, of which the following description,- in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to shuttle boxes for looms and more particularly to replenishing) shuttle boxes. V

uring weaving operation when the shuttle enters and leaves the shuttle box it is subjected to a deflection from its normal horizontal path, or is liable to jump as it is called. The top plate is designed to restrict the jumping tendency of the shuttle, or confine it within limits so that it may not jump entirely from the shuttle box. Since the shuttle, however, is made of wood usually, it is liable, to excessive wear and injury as it enters and leaves the shuttle box, and one of the purposes of the present invention is to provide a top plate of such construction an arrangement of the parts thereof that it will restrain the shuttle from the results of its jumping tendenciesand at the same time act non-injuriously upon the shuttle itself.

The replenishing shuttle box is usually provided with an opening in its bottom to permit a depleted filling carrier to be ejected from the shuttle anda filled carrier to be substituted therefor. The filled carrier usually enters the shuttle box and shuttle from above, with the result that the top plate must be so constructed'and arranged that it will not obstruct the free entrance of the filled carrier and yet operate to prevent the shuttle from jumping or being misplaced within the'shuttle box.

An important feature of the present invention, therefore, consists of atop plate which extends longitudinally of the shuttle box in overhanging but non-obstructing relation thereto, so that while it may act upon the top portion of the shuttle it will not prevent the free introduction ofthe filled carrier or bobbin, and in order to prevent injury to the shuttle the under surface of the top plate is provided with cushioning material which, at the entrance of the box,

may act the full width of the shuttle, but on the side of the shuttle box it may act upon the top of the side wall of the shuttle.

It is also desirable that the cushioning material be held in its overlying relation with respect to the lower face of the top plate in smooth and uniform relation thereto, and another feature of the present invention therefore consists in meansfor securing the cushioning material in its protecting position.

The invention and new combination of parts will best be made clear from the following description and the accompanying drawings of one good form of the invention.

In the drawings:

Fig. 1 is a perspective view of the shuttle box at the replenishing side of a loom provided with the present invention;

Fig. 2 is an enlarged sectional view taken on the line 22 of Fig. 1; and

Fig. 3 is a plan view showin more particularly thetop plate, and in t is instance the back side wall of the shuttle box.

In the drawings, the la 'l'is of usual construction and is provide with the shuttle box 2, which receives the shuttleat the end of its flight. The shuttle box 2 is provided with an 'openin 3, Fig. 2, through wh1ch the denuded bo bin may be ejected bythe replenishing mechanism.

In the present instance of the invention, the side wall 4 which constitutes the back wall of the shuttle box, is secured to the lay as usual and at its inner end is provided with a casting 5 which overlies the entrance to the shuttle box. The front wall or side 6 of the shuttle box is shown, in the present instance, as formed by a binder which may be pivotally mounted on the lay at 7 and normally pressed inwardly by a sprlng, such as 8, which in the present instance is shown as a leaf spring secured to the outer end portion of the lay or shuttle box at 9.

The construction thus far descrlbed is as usual in looms of this type, although ing 11 which, when the: shuttle is properly boxed, registers with the opening 3 for the free passage of the filling carrier as it is ejected from the shuttle during the replen ishing operation.

Mounted upon the shuttle box, and in the present instance shown as removably secured to the side wall 4 thereof, is the top plate 12 which extends longitudinally substantiall the full length of the shuttle box. At t e entrance of the shuttle box the top plate 12 is widened, as indicated, so that as the shuttle enters the box it may act efiectively to restrain any jumping move ment of the shuttle by acting throughout the width thereof; From the entrance of the shuttle box the top plate 12 gradually diminishes in width at 13 so that at the point 14, which is adjacent the head of the bobbin, the overhanging extent of the top plate will not interfere'with' the proper entrance of the filled carrier or bobbin into the shuttle. From the point 14, adjacent the head of the bobbin, the top plate 12 is narrowed as at 15, to present an overhang which may extend substantially the full length of the shuttle box from the point 14 and act upon the top of the side wall 16 of the shuttle as it moves to its full boxed position. The overhang of the top plate along the portion 15 is such that 'while' it may act upon the top of the side wall 16 of the shuttle, it will nevertheless offer no obstruction to the free passage of a full filling carrier or bobbin into the shuttle. The overhang may be substantially the same width as the side wall 16 of the shuttle, but a variation from its width may be permitted within limits so long as the overhang 15 does not obstruct the free ontrance of the filled carrier or bobbin into the shuttle during replenishing.

The top plate 12 at its widenedportion underlies the part 15' which may be conveniently cast as a portion of the side wall 4 of the shuttle box, so that at the entrance of the shuttle box the top plate 12 is substantially unyielding and acts effectively upon the shuttle to prevent jumping.

In order that the top plate may not-injuriously affect the Wood of the shuttle, the under surface of the top plate is covered with a cushioning material which may be" formed of leather or equivalent substance. In the present instance of the invention, the covering or facing of the top plate 12 extends throughout the full length of the top plate and is secured in its covering position between the top plate and the side wall 4 of the shuttle box to present no metallic part for contacting with the shuttle as it enters and leaves the box.

The cushioning material 17 is shown, in the present instance of the invention, as formed of leather or substantial thickness full bobbin is trans and body to present a good wearing surface, and is secured in place between the top plate 12 and the top of the side wall 4 by means of screws 18, which also serve as means for holding the top plate itself in its overhanging relation with the shuttle box.

At the entrance of the shuttle box the cushioning material or leather 17 is turned over the top of the top plate 12 as at 19 and is secured in place by means such as rivets or bolts 20 which constitute one ood form of means for holding the end of the cushioning material or leather to the top plate at the entrance of the shuttle box. The bolts or rivets 20, however, preferably do not extend through the bottom layer of the cushioning material or leather 17 so that no metallic surfaces are exposed to contact by the shuttle as it enters and leaves the box.

As indicated in Fig. 3, the top plate 12 has a portion cut away at 21 to present a shoulder which abuts against a side wall of the casing 5 under which the entrance e'nd'portion of the top plate extends. Similarly, the cushioning material or leather is cut away at 21 and extends over the undersurface of the top. plate frontward of the wall 22 of the casin 5. The togplate mayie conveniently notched sition, and overhangs downwardly when a erred to the shuttle.

From the construction described it will be a parent that the cushioning material whic overlies the under surface of the top plate presents a non-injurious contactmg surface for the shuttle and acts effectively to prevent the shuttle from jumping as it enters and leaves the box, andon the overhang 15 the cushioning material acts non-injuriously upon the top of the side wall 16 of the shuttle as it moves in and out of the box. I
